It seems the only answer is to stop using them... But you all knew that anyway - even if you struggle to admit it to yourself.

If you smoke cigarettes, or drink alcohol, or eat meat, or do anything wrong in your life (which like all of us YOU DO!), you can substitute this activity in instead of 'using the plastic bag'. But for now, let's stick with plastic.

Category #1: Evil

Would you use the plastic bag because it is bad for the environment...

This is doing the wrong thing because it is the wrong thing to do. Hopefully there aren't too many of these people out there.

Examples:

Slavery, genocide

Category #2: Ignorance

Do you know that the plastic bag is bad for the environment, but use it nonetheless.

Ignorance is when you know what you are about to do is not a good idea, but you do it anyway… This is because we don't care enough to go through the 'effort' of committing to the better alternative (unprepared!).

Examples:

Smoking cigarettes, drinking alcohol (to get drunk)

Category #3: The weak

The plastic bag... I'm sure there was something I read about it being... [pauses to think!]

“Excuse me, would you like a bag for this?”

“Oh, yes please”

Ah, it probably wasn't important...[fearing the conclusion]

Weakness is avoiding the situation altogether or hiding from the truth.
